ISOLATING THE ROLE OF LATERAL MIXING ON OCEAN ECOSYSTEM FUNCTIONING
This project uses the GFDL CM2Mc coupled climate model to simulate large-step function perturbations of CO2 to extract the magnitude of anthropogenic radiative forcing and distinguish biogeochemical processes driven by climate change versus those driven by natural variability. As an extension to our 2019 study, Anand Gnanadesikan, Marie-Aue Pradal, and I, once again utilize the representation of lateral mixing in modulating model response. However, this project examines the impact of changing diffusivity on the linearity of biogeochemical response.

OCEAN DEOXYGENATION ACROSS A SUITE OFÂ EARTH SYSTEM MODELS
In collaboration with Anand Gnanadesikan and Marie-Aude Pradal at Johns Hopkins University, this project set out to investigate the impacts of anthropogenic global warming on the distribution of ocean oxygen in Earth System Models. Because Earth System Models represent ocean mixing with specific parameters, we conducted a sensitivity study on how different lateral mixing coefficient parameterizations impact oxygen distributions.
The results of this study were published in the American Geophysical Union's Global Biogeochemical Cycles journal in 2019. Read here [LINK].
